Title:
PRECURSOR OF SINGLE-MOLECULAR-WEIGHT AMPHIPHILIC FLUORENE-AZOBENZENE OLIGOMER, OLIGOMER, SELF-ASSEMBLED FIBER, AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/155247
Kind Code:
A1
Abstract:
Provided are a single-molecular-weight amphiphilic fluorene-azobenzene oligomer, a self-assembled fiber, and a preparation method. The present invention diversifies and expands the studies of molecules having a backbone containing fluorine and azobenzene, and has guiding significance in the development of azobenzene-based and fluorene-based materials. The single-molecular-weight oligomer has good manufacturing performance and physical properties. By means of combining the iterative step-by-step growth strategy with an efficient copper(I) catalyzed azide-alkyne cycloaddition (CuAAC) reaction and accurately controlling the azobenzene position to precisely synthesize amphiphilic oligomers of different sequences, the present invention features easy-to-operate procedures and provides a theoretical basis for studies accurately investigating the relationship between the structure and the performance. By means of accurately controlling the internal accumulation and the external morphology of the nanoparticles through a downward self-assembly manner in a solution, a 1D/2D nanomaterial with specific functionality is constructed. In addition, the method uses chemical reagents that are stable in air, thus featuring ease of operation and high efficiency.
